LOCOMOTIVE.

SPECIFICATION forming part of Letters Patent No. 667,342, dated February5, 1901 Application filed October 19, 1900-. Serial No. 33,552. KNomodel.)

To fl, Hill/077D it rim/,7 concern.-

Be it known that I, JAMES E. SAGUE, a citizen of the United States,residing at Schenectady, in the county of Schenectady and State of NewYork, have invented certain new and useful Improvements inLocomotives,of which the following is a specification.

This invention relates to that class of 1000- motives in which thefire-box is made of extra width in order to obtain an ample grate areawithout necessarily increasing the length thereof. It is desirablethatthe fire-box should be located at the rear of the locomotive inorder that the fireman and engineer may be together. In such locomotivesit is necessary to provide one or more pairs of supporting or trailingwheels under the fire-box, and in order to obtain the greatest width offire-box and ash-pan the sides of the ash-pan should be as close aspossible to the inner sides of the trailing wheels. In the locomotivehereinafter described the axle-boxes of the trailing wheels are arrangedoutside the truckframe, by which construction the sides of the ash-panmay be arranged close to the inner sides of the trailing Wheels, thusgiving to the ash-pan a greater width than could be obtained where theaxle-boxes are arranged inside the wheels. Such an arrangement alsoprevents the journals of the trailing wheels from being heated by closeproximity to the ash-pan. The bearings are readily accessible foroiling, 850., and the lateral distance between the points of support isincreased, thus making the engine much steadier and freer from atendency to roll, as is the case where the axle-boxes are arrangedinside the wheels.

While, broadly stated, it is not new to arrange the axle-boxes of thetrailers outside the wheels, it is new to so arrange the axleboxes inconnection with improved devices employed by me for equalizing theweight, as hereinafterdescribed. Theequalizingmechanism is of animproved construction and arranged in an improved way. Springs areattached to the axle-boxes of the driving-wheels and to the trailers,and they are connected together by links and levers in such manner as toproperly distribute the weight. The axle-boxes of the driving-wheels arearranged inside the truck-frame, and special mechanism is employed by mefor connecting the springs attached to the axle boxes of the driverswith the springs attached to the axleboxes of the trailing wheels,which, as before stated, are arranged outside the truck-frame.

The details of construction will be hereinafter more fully described.

The subject-matter deemed novel will be setforth in the claims.

In the accompanying drawings, Figure 1 shows a side elevation of alocomotive embodying my present invention. Fig. 2 is a plan view of thetruck thereof. Fig. 3 is a detail view showing particularly the mannerof connecting the springs of the drivers with the springs of thetrailing wheels. Fig. 4 is a detail plan view of this mechanism, andFig. 5 shows a transverse section on the line 5 5 of Fig. 3.

The boiler A and cab B, with their appurtenances, are of usualconstruction. The firebox A and ash-pan A are mounted on a framesupported on driving wheels 0, trailing wheels D, and pilotwheels E. Themain frameis preferably continuous, the front ends of the side pieces Hthereof being secured to abuffer F,while the rear ends are connected bya cross-frame G. The frame H is formed with pedestals or guides H H forthe boxes 0 of the driving-wheels. Outside frame pieces or plates J areprovided, and each has a guide or pedestal cl extending over theaxle-box of the corresponding trailer. These frame pieces or plates Jare arranged outside the vertical plane of the trailing wheels over thetrailing axle, and the rear ends of the frame-pieces H also extend overthe trailing axle inside the wheels, as indicated, for instance, in Fig.2. Filling-pieces K are interposed between the outside frame-pieces Jand the adjacent sides of the frame-pieces H and are bolted thereto. Theoutside frame-pieces J and the rear ends of the main frame-pieces H arealso connected together between the cross-frame G and the trailing axleby means of bolts. Fillingpieces G are interposed between the rear endsof the outside pieces J and the rear ends of the frame-pieces H and aresecurely bolted thereto and to the cross-frame G, as indicated.

The construction which I have just described is not herein claimed aspart of my present invention, as substantially the same construction isshown and claimed in my application for patent, Serial No. 26,779, filedAugust 13, 1900. That application, however, shows different mechanismfor equalizing the weight or connecting the springs of the drivers withthe springs of the trailing wheels. In the presentinstance a spring M ismounted on top of the axle-box of each trailing wheel. The rear end ofeach spring is connected with a corresponding outside frame piece J bymeans of a link m. The front end of each spring M is connected by meansof a link N with a lever O, pivoted at 0 to a hanger P, depending fromthe truck-frame. The lever O is diagonally arranged. Its rear end, whereit is connected to the link N, is directly under the front end of thespring M. The front end of the lever 0, where it is connected to thespring S of the rear driving-wheel, is directly under the rear end ofthe spring S. Thus the lever 0 extends from the outside of theframe-piece J to the inside of the adjacent frame-piece H and beneaththese framepieces. The link N, it will be observed, is twisted at n inorder to obtain a proper pivotal connection at this end. The front endof the lever 0 may be slightly bent at 0 in order to obtain a pivotalconnection with the lower ends of the links T, which connect the frontend of the lever -O with the rear end of the spring S of the reardriving-wheel.

In the present instance the springs S Sare mounted on top of the axleboxes of the drivingwheels; but they may be otherwise attached thereto.Where they are mounted as shown in the drawings, the front end of therear spring S is connected by means of links U with a lever U, pivotedto the main frame. The front end of the lever U is connected by links'11 with the rear end of the spring S. The front end of the spring S isconnected by means of links a with a bracket 11. on the truck-frame. Thearrangement on opposite sides of the truck is precisely thenecessary toreduce the area of the ash-pan to accommodate the trailing axle.

The mechanism is simple and most effi ciently provides for theequalization of the weight in that class of'locoinotives embodying awide fire-box with the axle-boxes of the trailing-wheels arranged in adifferent vertical plane from the axle-boxes of the drivingwheels.

vI claim as my invention 1. The combination of the driving-wheels, theiraxles, the axle-boxes thereof arranged inside the wheels, the trailingwheels, their axles, the axle-boxes thereof arranged outside the wheels,springs attached to the axleboxes of the driving-wheels and to theaxleboxes of the trailing wheels, the truck-frame, diagonally-arrangedlevers pivoted in bearings thereon, and connections between the springsof the trailing wheels and drivingwheels, and said diagonally-arrangedlevers.

2. The combination of the driving-wheels, their axles, the axle-boxesthereof arranged inside the wheels, the trailing wheels, their axles,the axle-boxes thereof arranged outside the wheels, springs attached tothe axleboxes of the driving-wheels and to the axleboxes of the trailingwheels, the truck-frame, levers pivoted thereto, and extendingdiagonally'beneath the sides of the frame, links arranged outside theframe connecting the springs of the trailing wheels with thediagonally-arranged levers, and links inside the frame connecting thediagonally arranged levers with the springs of the driving-wheels.

3. The combination of the driving-wheels, their axles, the axle-boxesthereof, arranged inside the wheels, the trailing wheels, their axles,the axle-boxes thereof, arranged outside the wheels, springs attached tothe axleboxes of the driving-wheels, and to the axleboxes of thetrailing wheels, the main truckframe, the outside frame-pieces connectedtherewith, the diagonally-arranged levers, the rear ends of which arearranged outside the outside frame-pieces and which are con nected withthe springs of the trailing wheels, and connections between the frontends of the diagonally-arranged levers and the springs of thedriving-wheels.

In testimony whereof I have hereunto subscribed my name.
